To all whom it may concern Be it known that I, LEOPOLD GUGGEN BERGER, acitizen of the United States, and a resident of-Hastings-upon-Hudson,Westchester county, New York, have invented a new and useful Improvementin Window- Screens, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in window screens. Heretoforeserious objections have been offered to rolling window screens, and someof the objections were that the screens were likely to break, the edgeswere not held so as to make a'tight closure against insects, and theyhave been likely to accumulate dust and dirt. The object of my inventionis to produce an improved rolling window screen which can be suspendedin a window frame on a roller analogous to the ordinary shade roller,and can be raised and lowered like a shade, and further to provide aseries of guides which will hold the edges of the screen smooth andtight against the window frame so that no insects can get by, and alsoto provide an automatic cleaning device which will keep the screen freeof dust and which operates b simply raising and lowering it. Other ohjectsof my invention are to provide a guiding device which can be easilyattached to the sides of a window frame which will hold the screen inthe desired position, and which will also serve to guide and support theshade so that this will not flap and be displaced or torn by the wind. Apart of my apparatus also serves the purpose of a weather strip andanti-sash rattler. In general the object of my invention is to produce avery efiicient, simple, and easily attached rolling window screen whichwill be very convenient in use.

Reference is to be had to the accompanying drawin s forming a part ofthis specification, in w ich similar reference characters indicatecorresponding parts in all the views.

Figure 1 is a broken vertical section of a window provided with myimproved attachments.

Fig. 2 is a broken perspective view of the lower part of the window andscreen, parts being in section.

Fig. 3 is a broken sectional plan of the structure as applied to thewindow.

Fig. 4 is a broken elevation of the shade with the guiding attachmentsthereon.

Fig. 5 1s a broken sectional plan of the shade and guide, and

Fig. 6 is a development of one of the guldes.

I have shown my attachments in connection with the ordinary slidingwindow 10 arranged in a frame 11, but the invention is not confined toany particular form of window. I can use my rolling screen, however, inconnection with the ordinary shade 12 which rolls on a roller 13 in thecustomary manner. At the top of the window frame so as to insure closingthe entire window opemng, is a housing 14 which is open at the bottom asshown at 15, and in which is a roll 16 of screening material, and thican be either fabric or metal, and the roller can be any usual orpreferred type of spring roller. The screen 17 runs through the bottomopening of the housing, and on one side of the screen is held a brush 18which rubs against the screen surface, and-on the opposite side of theopening 15 the housing is prolonged to form a spring 19 which pressesthe screen against the brush, and so when the screen is moved up anddown the brush keeps it clean. The screen can be pulled down or allowedto spring up like an ordinary shade. To insure a tight fit on the sides,and to prevent any insects from getting in, the screen and also theshade preferably are provided with guiding devices which run in suitableguideways and which can be conveniently made from soft metal strips 20which can be readily doubled to shape. The strip has near one end and onopposite edges lugs 22 which can be forced through the material of thescreen 17 or shade 12, and then doubled over to fasten the strip inplace, and this part of the strip lies flat against the shade or screenas the case may be, while a portion is allowed to project to form anangle guide 21 (see Fig. 5). One member of the strip 23 extends at anangle to the shade or screen and is doubled over and returned uponitself, as shown at 24, while the part 25 of the strip lies flat againstthe shade or screen, and the end por tion 26 is thrust through thematerial and doubledover upon itself as shown clearly in Fig. 5, thisend portion 26 being preferably notched so that it will readily piercethe material. The important thing is to have the guide 21 substantiallyas shown, and obviously it can be provided in other ways than by bendingthe particular form of strip shown. It should project from the edge ofthe screen or shade so that when these,are rolled up the guides 21 oneither edge will not interfere with the roller, and the several guides21 are spaced apart at necessary intervals to perform their function ofholding the screen and shade in place.

The edges of the screen and shade run in vertical guideways 27 which canbe conveniently formed of sheet metal pressed to shape, but can beotherwise made if desired. The guideways 27 merge into chambers 28 (seeFig. 3) so that the edges of the shade and screen will run in theguideways 27, but the angleportions or guides 21 will move in thechambers 28 and thus prevent the screen or shade from going out of placeor being too easily removed. The screen and shade are kept spaced by avertical partition 29 which separates the two guideways 27 and whichform a part of the base portion 30 lying flat against the vertical sideof the window frame. It will be seen that this member comprising theparts 27, 28, 29 and 30 can be very easily formed of sheet metal. Theside portions of this member are preferably pressed together to produceflanges 31 through which screws 32 Or the like can be passed to fastenthe guide member to the window frame.

To effect a suitable closure at the bottom of the screen, it ispreferably provided with a strip 33 which is slotted along the top edgeas shown at 34 in Figs. 1 and 2, and the lower edge of the screen may beextended into the slot and suitably fastened. The under edge of thestrip 33 is likewise slotted as shown at 35 so as to fit on over the rib36 when the screen is pulled down to the window bottom, thus effecting atight closure. This rib 36 can be applied to the window ledge in anyconvenient way, but I preferably form it on the base 37 which extendsinward to a point near the sash of the window where it is turned up toform a flange 38, and when the window is closed, the flange 39 on thestrip 40 which is attached to the window sash, as shown clearly in Figs.1 and 2, overlap the flange 38. Thus a tight closure is effected and theoverlapping fianges 38 and 39 form an excellent Weather strip andanti-rattler. It will be seen also that the vertical guides at the sidesof the window may also serve as weather strips, and when the structureis in position both shade and creen can be used as a shade is generallyused, all flapping in the wind is avoided, and a smooth tight closureagainst insects is had.
